i think the tanks i keep them in is fine,i use a gravel vac about 3 times a week but i do a 100% water change & scrub every thing in the tank.the place i bought my orange & my blue marble kept them in cups,litteraly cups,that made wal-marts size & cleanliness look good.& they were only about 1 inch full 
theirfins were sticking out 
.i took one of the empty cups and filled their cups enough that they could move,so he couldnt even swim right when i got him home because he didnt have enough muscles since he couldnt swim in the 4 oz cups that he was in that were only filled halfway. there was already about ten dead ones :sad: ,i went to the front & told the lady if she didnt chanch it iwould! she changed it,& i asked her how often they fed the bettas,she said once a WEEK .so the tanks i keep them in is ok.read my other tread about ghost shrimp/bettas.
